The StcsChan class provides facilities for reading and writing
IVOA ``STC-S'' descriptions. STC-S (see http://www.ivoa.net/Documents/latest/STC-S.html) is a linear string
syntax that allows simple specification of the STC metadata describing a
region in an astronomical coordinate system. AST supports a
subset of the STC-S specification, allowing an STC-S description of a
region within an AST-supported astronomical coordinate system to be converted
into an equivalent AST Region object, and vice-versa. For further
details, see the full description of the StcsChan class in
.
